FASTENING- FOR SHIRT-STUDS.

Specification of Letters Patent No. 25,386, dated September 13, 1859.

To all whom it may concern:

Be it known that I, BARNES CLAYTON, of the city of Philadelphia, in theState of Pennsylvania, have invented a new and Improved Fastening forShirt-Bosom Studs; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, in which- Figuresl and 2 are, respectively, enlarged back and side views of a.shirt-bosom stud with the improved fastening applied theree to; andFigs. 3` and t vertical longitudinal sections of the same-like lettersindicating the same parts when on the different figures.

The nature of my invention consists in the combination and arrangementof a hollow, sliding case and a contained spring, with the tie or postwhich rigidly connects the front, or ornamental part of the stud to itsback or fastening-bar, in such a manner that the said sliding case willyield to pressure so as to admit of a ready and convenient applicationof the stud, and afterward, by the re-action of the spring when thepressure is removed, so change its relative position in respect to thefastening bar as to cause the latter to prevent the stud from beingremoved from the garment in an illegitimate manner or by a direct pull.

To enable others skilled in the art to understand and make my invention,I will proceed to describe, more fully, its construction and mode ofoperation.

In the drawings A, represents the hollow, sliding case; B, the springcontained within it; C, the front, or ornamental part of the stud; D,the back or fastening bar; and E, the tie, or post, which rigidlyconnects the two parts, C and D, together.

The bar (D) is a rigid, slender piece of metal fixed to the rear side ofthe ornamental part (C), by means of the tie or post (E), so as toremain parallel with, and at a short distance from, the said side,substantially as shown in the drawings.

The case (A) is a. short, Hat tube, of thin metal plate, which surroundsthe tie (E), and slides between and in contact with the two parts (C andD)-its inner end einbracing the rounded inner edge of the bar (D) so asto confine its motion in the direction of the length of the latter. Asan additional means of guiding or steadying the sliding motion of thiscase (A), its opposite end also may'embrace a fin f, which may be fixed,for the purpose, on the rear side of the part The spring (B) may be madeeither spiral, or zigzag, in form, and, when placed within the case (A),should press against both the tie (E) and the upper side of the oase (A)with sufficient force to hold the lower side of the said case in contactwith the tie (E), and thus permit both ends of the bar (D) to projectbeyond it-as shown in Figs. l, 2, and Ll--and at the same time be ofsuflicient delicacy, as to strength and elasticity, to admit of itsbeing sufliciently compressed, in the act of introducing or applying thestud, to allow the lower side of the case (A) to be brought, by amoderate pressure, flush wit-h the lower end of the bar (D)-as shown inFig. 3.

Operation: The red lines in Figs. 3 and 4 indicating the two parts of ashirt bosomthe ornamental part (C) of the stud is to be held between theoperators linger and thumb, and the upper end of the bar (D) passedthrough the holes, appropriated therefor in the garment, and by hiseXertion of a moderate pressure, upward, the case (A) is caused to slidedownward until its lower side has become flush with the lower end of thebar (D)-as shown in Fig. 3-when, by his simply pressing the studbackward, the lower end of the said bar (D) is also caused to passthrough the holes in the garment, and the stud being then immediatelyafter released from the thumb and linger of the operator, the reactionof the spring (B) brings the said bar and case into their normalrelative positions with each other-as shown in Fig. 4,-and so secure thestud in position as required.

It will readily be perceived that this is ay Very superior fastening forshirt bosom studs, and other similar articles of jewelryit being simpleand durable in its c0nstruc tion, and yet neat, perfectly effective, andI (E) and the bar (D)-the same being ai"- of very easy and convenientapplication and ranged to Operate together substantially in 10 removal.the manner and for the purpose set forth What I claim as my inventionand desire and described. ,r3 to secure by Letters Patent, in the hereinBARNES CLAYTON.
